An factbox on nuclear accidents like Fukushima vs Three Mile Island:

THREE MILE ISLAND:

* Three Mile Island is the worst nuclear power accident in U.S. history even though it resulted in no injuries.

* About half the reactor core in one unit at the Three Mile Island plant in Pennsylvania melted due to the loss of coolant. The other unit suffered no damage and still operates today.

FUKUSHIMA DAIICHI:

* Three units at the Daiichi nuclear plant suffered a loss of coolant to their reactors following a massive earthquake and a devastating tsunami. The fuel rods in at least one unit were damaged due to the loss of coolant and suffered a partial meltdown.

* The plant vented a small amount of radiation to release pressure in the units' containment, raising the levels in the immediate vicinity of the plant above the legal limit. The plant also suffered an explosion caused by a buildup of hydrogen that collapsed the roof on at least one of the units.

@jennico Oh, so that's why NHK always refers to them as Fukushima number 1 and number 2, respectively.

All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.

[There is no update from the previous press release.]

Unit 1(Shut down)- Reactor has been shut down. However, the unit is under inspection due to the explosive sound and white smoke that was confirmed after the big quake occurred at 3:36PM. - We have been injecting sea water and boric acid which absorbs neutron into the reactor pressure vessel.

Unit 2(Shut down)- Reactor has been shut down and Reactor Core Isolation Cooling System has been injecting water to the reactor. Current reactor water level is lower than normal level, but the water level is steady. After fully securing safety, measures to lowering the pressure of reactor containment vessel has been taken, under the instruction of the national government.

Unit 3(Shut down)- Reactor has been shut down. However, as High Pressure Core Injection System has been automatically shut down and water injection to the reactor was interrupted, following the instruction by the government and with fully securing safety, steps to lowering the pressure of reactor containment vessel has been taken. Spraying in order to lower pressure level within the reactor containment vessel has been cancelled.- After that, safety relief valve has been opened manually, lowering the pressure level of the reactor, which was immediately followed by injection of boric acid water which absorbs neutron, into the reactor pressure vessel.

Unit 4 (shut down due to regular inspection)- Reactor has been shut down and sufficient level of reactor coolant to ensure safety is maintained.- Currently, we do not believe there is any reactor coolant leakage inside the reactor containment vessel.

Unit 5 (outage due to regular inspection)- Reactor has been shut down and sufficient level of reactor coolant to ensure safety is maintained.- Currently, we do not believe there is any reactor coolant leakage inside the reactor containment vessel.

Unit 6 (outage due to regular inspection)- Reactor has been shut down and sufficient level of reactor coolant to ensure safety is maintained.- Currently, we do not believe there is any reactor coolant leakage inside the reactor containment vessel.

Casualty- 2 workers of cooperative firm were injured at the occurrence of the earthquake, and were transported to the hospital.- 1 TEPCO employee who was not able to stand by his own with his hand holding left chest was transported to the hospital by an ambulance.- 1 subcontract worker at important earthquake-proof building was unconscious and transported to the hospital by an ambulance.- The radiation exposure of 1 TEPCO employee, who was working inside the reactor building, exceeded 100mSv and was transported to the hospital.- 2 TEPCO employees felt bad during their operation in the central control rooms of Unit 1 and 2 while wearing full masks, and were transferred to Fukushima Daini Power Station for consultation with a medical advisor.- 4 workers were injured and transported to the hospital after explosive sound and white smoke were confirmed around the Unit 1.- Presence of 2 TEPCO employees at the site are not confirmed

Others- We are currently coordinating with the relevant authorities and departments as to how to secure the cooling water to cool down the water in the spent nuclear fuel pool.- We measured radioactive materials inside of the nuclear power station area (outdoor) by monitoring car and confirmed that radioactive materials level is higher than ordinary level. Also, the level at monitoring post is higher than ordinary level. We will continue to monitor in detail the possibility of radioactive material being discharged from exhaust stack or discharge canal. The national government has instructed evacuation for those local residents within 20km radius of the periphery because it's possible that radioactive materials are discharged.

- We will continue to take all measures to restore the security of the site and to monitor the environment of the site periphery.
